Fentanyl exposure throughout pregnancy and weaning does not influence dam weight (A) or daily liquid intake (B). (C) Fentanyl exposure did not adversely affect maternal care behaviors during the critical period from postnatal days (PDs) 1 to 7. (D) Fentanyl-exposed dams displayed latencies to pup retrieval on PD 8 that were indistinguishable from controls. Dams exposed to fentanyl during pregnancy had smaller litters (E) and a higher litter mortality rate, compared with controls (F). Data depict medians and 95% confidence intervals
